Production Introduction
4130 steel tube, also known as chrome moly tube, is a general-purpose alloy steel tube with chrome and molybdenum as the main alloying elements. It is mainly produced as cold-drawn seamless tube, complying with international standards such as ASTM A519 and AMS-T-6736 (formerly MIL-T-6736), and domestic standard GB/T 17396-2022. It is widely recognized in global markets for its reliable quality and stable performance,4130 steel tube is commonly used for producing bike and electric bicycle.
The standard is listed below
AE 4130/JIS SCM430 25crmo4 1.7243 l alloy seamless steel tube.
